This invention relates to anautomatic sprayer trees being sprayed.

- 'An additional object'is the provision in such .a device of improved means whereby theiangle 2 Claims. (Cl. 29937) of the nozzle relative to the spray apparatus may I be readily adjusted.

' Still further objects reside in the combinations of elements, arrangements of parts, and features of construction, all as'will be more fully pointed out hereinafter; and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a rear elevational plan view of a truck or the like having one form of automatic spraying apparatus including features of the instant invention mounted thereon.

Figure 2 is an enlarged detail view of one of the nozzles and the mounting means therefor comprising a feature of this invention.

Figure 3 is an enlarged side elevational view of the mounting means disclosed in Figures 1 and 2.

Figure 4 is a top plan view of the detail shown in Figure 3.

Figure 5 is a sectional view taken substantially along the line 55 of Figure 4 as viewed in the direction indicated by the arrows.

Figure 6 is an enlarged sectional view taken substantially along the line 6-6 of Figure 5.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings, and more particularly to Figure 1, there is generally indicated at I!) a truck body comprised of a conventional frame II and including a rear axle l2 and driving wheels I3, as well as the other elements of such a vehicle of conventional construction, (not shown). Mounted on the truck frame H is a storage tank l5 adapted to certain suitable spray fluid, a pump l6 of any conventional design, and a driving motor ll, including a drive shaft l8, likewise of conventional design.

An outlet pipe extends from a suitable outlet 2l extending from the storage tank I5 upwardly in vertical alignment with the truck body l0 and terminates in a closure cap 22. Suitwith respect to each other. -vided with suitable apertures thereflirough is secured as by bolts or screws 34 to plate 21 and able flexible connections 23 extend from outlets in the pipe 24 to spray nozzles 25 of any desired pe. r

Nozzles 25 are secured to pipe 20 as by clamps generally indicated at 26.

Clamps 2B are, as best shown in Figure 3, each comprised-of a pair of plates 21 and 28. Plate 21,- is as best shown in Figure 4 provided with'a pair of arcuate-grooves 29 adjacent its, periphery through which extend bolts 30 which likewise extend through suitable apertures in plate 28, adapted to be secured in position as by'nuts 3i, thus'providing a releasable connection between the two plates'2l and-28, whereby upon loosening of the nuts 3| the two plates may be rotated A bracket 32pmis adapted to surround a portion of nozzle 25 in order to secure the same-in relatively rigid related assembly with plate 21.

Secured to the underside of plate 28, is a strap iron t5 interposed between plate 28 and a supporting member 36, plate 28, iron 35 and support 36 being secured together as by bolts 38 passed through suitable apertures therein, and countersunk so as to be flush with the upper surface of plate 28, and nuts 39. Supporting member 36 is provided with a longitudinally extending semi-circular groove 40 in its base corresponding with a similar groove M in a clamping member 42 adapted to be secured to'member 35 as by bolts 43. A supporting rod 45 is adapted to pass through the cylindrical bore formed of grooves 40 and 4|, in such manner that the plate assembly and its associated supporting members are free to pivot thereabout. The bracket assembly is held in position on rod 45, as by means of collars 46 and washers 41, collars 46 being secured on rod 45 as by means of set screws 48.

The opposite end of rod 45 terminates in a, circular clamp 50 having projecting lugs 5! through suitable apertures 52 in which is adapted. to be passed a locking bolt 53 and nut 54, clamp 59 being adapted to be positioned around pipe 20.

From the foregoing it will now be seen that the nozzles 25 may be adjusted angularly, in a horizontal plane with respect to pipe 20, by virtue of the adjustable feature of plates 2'! and 28, and that the nozzles and their associated assemblies are free to oscillate in a vertical direction, by virtue of the pivotal connection of rod 45 with the plate assembly 26.

Referring back now to strip iron 35, it will be seen, as best shown in Figures 4 and 5, that the same is twisted as at 66 from a horizontal to a vertical plane. Secured to vertical portion 60 as by suitable bolts 6! are vertically extending sectional iron strips 62, each provided with a plurality of holes or apertures 53 therefor to permit adjustment as may be required. The lower ends of strips 62 are secured as by pivots 65 to a bellcrank lever 66 pivotally mounted as by a'pivot 61 on pipe 20. It will now be seen that pivotal movement of bellcrank member 66, occasions f Tvertical reciprocatory movement of member 62 "and consequent oscillatory movement of nozzles 25, it here being pointed out that any desired number of nozzles 25 and their related mounting assemblies, can be mounted on pipe 20, and on opposite sides thereof, all those nozzles on any one side of the pipe being operated by one of irons 62.

The means for oscillating the nozzles through bellcrank member 66, include an extending portion 68 of the member to an extremity of which is pivotally secured as on a pivot 69 an arm 18 the opposite end of which is pivotally secured as on a pivot H to a timin disk 1.2 rotatably mounted on and secured to the drive shaft l8 of motor ll. Thus it will be seen that as the motor turns over the disk 12 is rotated, and arm H consequently moved thereby to provide oscillatory movement of bellcrank lever 65.

Means are also provided for varying the speed of oscillation of the nozzles 25, such means taking the form of a plurality of holes 13 through timing disk '12 and spaced at varying distances from the periphery thereof. Thus it will be seen that according to the hole or aperture 13, in which pivot H is seated, and the corresponding distance from drive shaft l8 of pivot H being thus determined, the speed of oscillation of the nozzles will be varied as desired.

From the foregoing it will now be seen that there is herein provided a device accomplishing all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiments hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. In a mounting for a nozzle adapted to be mounted in a pipe connected to a, source of fluid,

means for mounting said nozzle for oscillation in a vertical plane with respect to said pipe, and means .for varying the angular relation of said nozzle to said pipe in a horizontal plane, said last-mentioned means including a pair of plates,

one of said plates being secured to said nozzle, and the other of said plates being secured to said mounting means, and means for varying the relative position of said plates with respect to each other in a horizontal plane.

2. In a mounting for a nozzle adapted to be mounted in a pipe connected to a source of fluid, means for mounting said nozzle for oscillation in a Vertical plane with respect to said pipe, and means for varying the angular relation of said nozzle to said pipe in .a horizontal plane, said last-mentioned means including a pair of plates, one of said plates being secured to said nozzle, and the other of said plates being secured to said mounting means, means for varying the relative position of said plates with respect to each other in a horizontal plane, and means for securing said plates in adjusted position with respect to each other.
